Introduction
Borax is alkaline, and direct contact may disrupt the skin's acid-base balance, causing stinging, itching, or a burning sensation. Prolonged exposure can lead to dry, rough skin and even cracking. If the skin is broken, borax may be absorbed through the wound, leading to local redness, pain, or infection. Some individuals are allergic to borax, and contact may result in rashes, blisters, or swelling.

Borax can be harmful to the skin under normal circumstances and may cause irritation or allergic reactions upon contact. If any abnormalities occur, medical attention is recommended. Detailed analysis is as follows:

Borax is alkaline, and direct contact may disrupt the skin's natural pH balance, leading to stinging, itching, or a burning sensation. Prolonged exposure can result in dry, rough skin, and even cracking. If the skin has open wounds, borax may be absorbed through the injury, causing local redness, pain, or infection. Some individuals are allergic to borax; contact may trigger rashes, blisters, or swelling, and in severe cases, systemic symptoms may occur.

Special populations should exercise extra caution. Children have delicate skin and are more prone to inflammation or allergic reactions after exposure. Pregnant women often have heightened skin sensitivity, and borax absorption through the skin could potentially affect the fetus. Elderly individuals have weakened skin barrier function, increasing their risk of skin damage. Patients with pre-existing skin conditions may experience worsened symptoms and delayed recovery if exposed to borax.

To prevent harm, avoid direct contact with borax. Wear gloves when using products containing borax, and wash hands thoroughly afterward. If accidental contact occurs, immediately rinse the area with plenty of water and monitor for skin reactions. Seek medical help promptly if symptoms persist or worsen.

Can decorative iron used for nail art cause tetanus?
Whether decorative iron used in nail art can cause tetanus depends on whether the skin is broken. Simply touching intact skin usually does not lead to infection, but if there is a skin wound and it comes into contact with contaminated decorative iron, there may be a risk. To reduce the risk, check the condition of your hands before getting a manicure and treat any skin damage first; choose clean, rust-free decorative iron, and clean tools promptly after use.

What does it mean when cupping causes bleeding or fluid discharge?
Cupping-induced discharge of bloody fluid primarily results from the rupture of local capillaries due to negative pressure, leading to a mixture of blood and tissue fluid oozing out. A small amount of light red fluid is usually a normal physiological response; however, if there is excessive bleeding, dark red blood, or pus, it may indicate local inflammation, blood stasis, or skin damage. In cases of abnormal bleeding, prompt medical evaluation is necessary.

What does it mean if cupping leaves very dark marks?
Darker cupping marks usually indicate poor local circulation of qi and blood, more severe blood stasis, and may also suggest a significant presence of cold and dampness in the body. If the dark marks persist for a prolonged period or are accompanied by abnormal symptoms such as local pain, swelling, or skin damage, medical evaluation should be sought promptly. When the circulation of qi and blood is impaired, metabolic waste in local tissues cannot be effectively removed, making it easier for blood stasis to develop.

Does pears need to soften before eating?
After ripening, the pear's flesh becomes tender, soft, juicy, and sweeter, making it easier to chew and digest—ideal for elderly people, children, or those who prefer a soft texture. However, take note: if the pear has become soft due to prolonged storage or skin damage, especially when accompanied by mold, an unpleasant odor, or flesh decay, it should not be eaten to avoid gastrointestinal discomfort.

When treating children, use even gentler pressure to avoid injuring the finger joints.
